Where round stone areas work
Circles show up around fire pits, under swing sets, around trees and as seating areas. Steel or paver edging keeps the round shape crisp and holds loose stone in place. Do not pile stone against tree trunks; leave a gap at the base.

Ordering and delivery
Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. The scale ticket is the real weight; tons per yard here is a planning figure.
Measuring the area
Measure length and width in feet at a few points and use the largest figures, since real sites are rarely square. For odd shapes, split the area into rectangles and circles, work out each one and add them together. Depth is the number most people underestimate: drive a stake, run a level string and measure down to the dug-out surface in several spots.
Planning the cost
Quarries and landscape suppliers set their own prices, and they change by region and season. Get the price per ton, the delivery fee and the minimum order. If two products will both work, compare cost per square foot at your depth rather than cost per ton.
